Distant boyfriend


Ive been in a relationship with my boyfriend a month and this last week hes been really distant.

We usually see each other every other day but i've only seen him once this week which is odd but i asked him if he wanted to come see me and he said he was ill but went for a bike ride three times for a couple of hours. And i went to a restaurant with a few friends and my older brother. And he literally visited us to see my brother. And we had arranged to go out for the afternoon today but he bailed to go for another bike ride with my Brother.

Im so annoyed at him but i feel like im overreacting about it. What do i do?
